Description

Technical Field

[0001] The present invention relates to the technical field of material loading, in particular to a material loading device. Background Art

[0002] Glass bricks have been fully automatically produced. The only manual operation currently required is the loading of glass bricks, including loading on flatbed trucks and loading in containers. The most labor-intensive part is loading the glass bricks into containers. Currently, there are three ways to load boxed goods: one is to use a forklift to deliver the pallet to the container and manually load it; the second is to use a conveyor belt to deliver it to the vehicle and then use a robot to load it; the third is to use a conveyor belt to deliver it to the vehicle, and then use a machine to automatically arrange the goods in the vehicle and push them row by row.

[0003] During manual loading, each box of glass bricks is placed according to the preset arrangement direction. The general placement requirements for the arranged glass bricks are that the minimum distance from both sides to the container edge is 24mm, the minimum distance when entering the container door is 16mm, the minimum distance from the top glass brick to the top of the container is 32mm, and the height of the container lintel is 100mm. Since the glass bricks are arranged very closely and the space in the container is limited, except for the first manual loading method, the other two automated methods cannot complete the automatic loading of glass bricks in a compact space using current technical solutions.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise expressly specified or limited.

[0030] See Figure 1 This embodiment discloses a material loading device, including a loading device and a fence device. The loading device is used to transport materials, and the fence device is arranged in the cargo compartment of a truck to enclose the materials.

[0031] See Figures 2 to 4 The loading device includes a base 1, a rotating mechanism 2, a first lifting mechanism 3, a fixed seat 4, a feeding mechanism 5, a second lifting mechanism 6, a shovel fork 7, a pushing mechanism 8, a first rangefinder 9 and a second rangefinder 10.

[0032] The base 1 is provided with a first linear slide assembly 11 at its bottom, enabling linear motion on the first linear slide assembly 11, facilitating cargo handling. The first lifting mechanism 3 is rotatably mounted on the base 1 via a rotating mechanism 2. A fixed base 4 is secured to the lifting end of the first lifting mechanism 3. A feeding mechanism 5 capable of horizontal telescopic motion is mounted on the fixed base 4. The feeding end of the feeding mechanism 5 is connected to a shovel fork 7 via a second lifting mechanism 6. The shovel fork 7 is provided with a pushing mechanism 8 for pushing material from the shovel fork 7 onto a fence device within the cargo compartment.

[0033] A set of first distance meters 9 are fixed to the left and right ends of the fixed seat 4 near the side of the fork 7, respectively, for detecting the distance between the feeding end of the feeding mechanism 5 and the cargo compartment door. A set of second distance meters 10 are also fixed to the side surfaces of the two ends of the feeding end of the feeding mechanism 5, respectively, for detecting the distance between the feeding end of the feeding mechanism 5 and the two side walls of the cargo compartment. Specifically, the fixed seat 4 is driven to rotate by the rotating mechanism 2, which drives the feeding mechanism 5 to rotate. When the two sets of first distance meters 9 detect that the distances between the two ends are equal, it means that the feeding end of the feeding mechanism 5 is parallel to the cargo compartment door, and the operation of the rotating mechanism 2 is stopped. Then, the first linear sliding assembly 11 is driven to drive the base 1 to move linearly. When the two sets of second distance meters 10 detect that the distances between the two ends are equal, the operation of the first linear sliding assembly 11 is stopped. At this time, the feeding end of the feeding mechanism 5 is at the vertical center position of the cargo compartment, and then the second lifting mechanism 6 is driven to drive the feeding mechanism 5 to move vertically to a height capable of conveying materials.

[0034] Furthermore, a third laser rangefinder (not shown) and a camera (not shown) are provided at the end of the feeding mechanism 5. The third laser rangefinder is used to measure the height of the truck cargo compartment. After the truck position detection is completed, the camera recognizes the car license plate and compares the measurement data with the registration data.

[0035] See also Figure 2 The rotating mechanism 2 includes a rotating fixed seat 21, a first telescopic electric cylinder 22 and a turntable 23. The rotating fixed seat 21 is fixed on the base 1, and the turntable 23 is rotatably arranged on the base 1. One end of the first telescopic electric cylinder 22 is hinged to the rotating fixed seat 21, and the other end is a telescopic end hinged to the bottom of the first lifting mechanism 3. The first lifting mechanism 3 is fixed on the turntable 23.

[0036] Specifically, by driving the first telescopic electric cylinder 22 to extend and retract, the first lifting mechanism 3 is driven to rotate on the base 1 under the action of the turntable 23, and the provision of the first telescopic electric cylinder 22 can improve the rotation accuracy of the first lifting mechanism 3.

[0037] See Figure 3The first lifting mechanism 3 includes a lifting base 31, an X-shaped lifting frame 32, a second linear sliding assembly 33, a third linear sliding assembly 34, and a second telescopic electric cylinder 35. The bottom surface of the lifting base 31 is hinged to the output end of the first telescopic electric cylinder 22. The second linear sliding assembly 33 and the third linear sliding assembly 34 are respectively provided on the lifting base 31 and the fixed seat 4. One end of the lower part of the X-shaped lifting frame 32 is hinged to the lifting base 31, and the other end is hinged to the sliding end of the second linear sliding assembly 33. One end of the upper part of the X-shaped lifting frame 32 is hinged to the fixed seat 4, and the other end is hinged to the sliding end of the third linear sliding assembly 34. One end of the second telescopic electric cylinder 35 is hinged to the lifting base 31, and the other end is hinged to the upper part of the X-shaped lifting frame 32. The second telescopic electric cylinder 35 drives the fixed seat 4 on the X-shaped lifting frame 32 to rise or fall.

[0038] See Figures 4 to 6 The feeding mechanism 5 includes a sliding frame 51, a fourth linear sliding assembly 52, a conveyor belt assembly 53, a conveying motor 54, a feeding frame 55, a first connecting block 56 and a second connecting block 57. Multiple sets of sliding frames 51 are stacked up and down. In this embodiment, four sets of sliding frames 51 are provided, but it is not limited to four sets. The specific number can be set according to actual needs; the sliding frames 51 adjacent to each other are connected by the fourth linear sliding assembly 52, so that the upper layer of sliding frames 51 can make horizontal linear motion on the lower layer of sliding frames 51. One end of the bottom sliding frame 51 is hinged on the fixed seat 4, and the other end is fixed to the support block 4 on the fixed seat 4. 1 is supported, and each group of sliding frames 51 is provided with a group of conveyor belt assemblies 53 along its movement direction. The upper sliding frame 51 among adjacent sliding frames 51 is connected to the conveyor belt on the conveyor belt assembly 53 on the lower sliding frame 51 through a first connecting block 56, and the lower sliding frame 51 among adjacent sliding frames 51 is connected to the conveyor belt on the conveyor belt assembly 53 on the upper sliding frame 51 through a second connecting block 57. A conveying motor 54 is fixed to the bottom sliding frame 51 and connected to the conveyor belt assembly 53 on the sliding frame 51. A feeding rack 55 is fixed to the top sliding frame 51, and a second lifting mechanism 6 is fixed on the feeding rack 55.

[0039] Specifically, the driving conveying motor 54 drives the transmission belt on the conveyor belt assembly 53 to rotate. Since the transmission belt on the conveyor belt assembly 53 is connected to the second-layer sliding frame 51 through the first connecting block 56, the second-layer sliding frame 51 moves on the fourth linear sliding assembly 52 on the bottom sliding frame 51. At the same time, since the bottom sliding frame 51 is connected to the second-layer sliding frame 51 through the second connecting block 57, the conveyor belt in the conveyor belt assembly 53 on the second-layer sliding frame 51 is transmitted, and then the third-layer sliding frame 51 moves on the fourth linear sliding assembly 52 on the second-layer sliding frame 51. Based on the same principle, the top sliding frame 51 moves on the fourth linear sliding assembly 52 on the third-layer sliding frame 51, thereby driving the movement of the feeding rack 55.

[0040] Furthermore, rollers 58 are provided at both ends of the feeding rack 55, and two groups of first pressure sensors 59 are provided on the fixed seat 4 below the bottom sliding rack 51; specifically, when there is material on the shovel fork 7, the sliding rack 51 is supported by the support block 41, and the first pressure sensor 59 also receives the pressure of the sliding rack 51, and then the shovel fork 7 is transported into the cargo compartment through the feeding mechanism 5, and then the first lifting mechanism 3 is driven to descend. When the first pressure sensor 59 no longer receives the pressure of the sliding rack 51, the roller 58 is placed in the fence device in the cargo compartment, and the support block 41 does not support the sliding rack 51. One end of the sliding rack 51 is supported by the fixed seat 4, and the other end is supported by the roller 58, and then the transmission motor 54 is driven to drive the four groups of sliding racks 51 to move into the cargo compartment. Under the rolling action of the roller 58, the forward thrust of the sliding rack 51 is greatly reduced.

[0041] Furthermore, guide assemblies 14 are provided at both ends of the topmost sliding frame 51. The guide assemblies 14 include a rocker arm 141, a mounting plate 142, a guide roller 143 and a third telescopic electric cylinder 144. One end of the rocker arm 141 is hinged to the sliding frame 51, and the other end is connected to the mounting plate 142. A plurality of guide rollers 143 are provided at the end of the mounting plate 142 away from the rocker arm 141. One end of the third telescopic electric cylinder 144 is hinged to the sliding frame 51, and the other end is a telescopic end and is hinged to the end of the rocker arm 141 close to the mounting plate 142. Specifically, during the movement of the sliding frame 51, the guide rollers 143 are attached to the side of the fence device for guidance.

[0042] Furthermore, the support block 41 is L-shaped, and the horizontal sections of the two groups of support blocks 41 are arranged relative to each other and are used to support the bottom sliding frame 51. The inner sides of the vertical sections of the two groups of support blocks 41 are arranged relative to each other and are provided with second pressure sensors (not shown in the figure). When one of the groups of second pressure sensors receives pressure sensing, it indicates that the sliding frame 51 is offset, and the sliding frame 51 is driven to move back by driving the third telescopic electric cylinder 144 to extend and retract until the second pressure sensor no longer receives pressure and the extension and retraction of the third telescopic electric cylinder 144 is stopped.

[0043] Furthermore, a camera (not marked in the figure) is fixed on the feeding rack 55 to detect whether the material is tilted or protruding, and to alarm if it exceeds the limit.

[0044] See Figure 4 The second lifting mechanism 6 includes a lifting motor 61, a worm gear assembly 62, a screw 63 and a fifth linear sliding assembly 64. The lifting motor 61 is horizontally fixed to the feeding end of the feeding rack 55. The output end of the lifting motor 61 is connected to the screw 63 vertically arranged on the feeding rack 55 through the worm gear assembly 62. One end of the shovel fork 7 is threadedly connected to the screw 63. Two groups of fifth linear sliding assemblies 64 are vertically and parallelly arranged at the feeding end of the feeding rack 55. The sliding ends of the two groups of fifth linear sliding assemblies 64 are connected to the shovel fork 7. The lifting motor 61 drives the screw 63 to rotate, thereby driving the shovel fork 7 to move vertically up and down on the feeding rack 55.

[0045] See also Figure 4 The pushing mechanism 8 includes a sixth linear sliding component 81, a pushing plate 82, and a pushing electric cylinder 83. Two groups of sixth linear sliding components 81 are arranged at both ends of the shovel fork 7 along the feeding direction of the feeding rack 55. The output end of the sixth linear sliding component 81 is connected to the pushing plate 82, and the fixed end of the pushing electric cylinder 83 is fixed on the shovel fork 7. The output end of the pushing electric cylinder 83 is connected to the pushing plate 82; specifically, when the material is glass bricks, the glass bricks are directly stacked on the shovel fork 7 without a pallet at the bottom. When the shovel fork 7 is recovered, the pushing electric cylinder 83 is driven to push the pushing plate 82 away from the shovel fork 7 to push out the glass bricks on the shovel fork 7.

[0046] It should be noted that, in this embodiment, the first linear sliding module 11, the second linear sliding module 34, the third linear sliding module 35, the fourth linear sliding module 52, the fifth linear sliding module 64, and the sixth linear sliding assembly 81 are all linear sliding assemblies that can be directly purchased on the market.

[0047] See Figure 7 and Figure 8The fence device includes a support seat 13 and a fence 12. Multiple groups of fences 12 are arranged at both ends of the support seat 13. The fences 12 are L-shaped. Through holes 131 are provided at both ends of the support seat 13. The bottom surfaces of both ends of the support seat 12 are hinged to the horizontal sections 121 of the fences 12. The vertical sections 122 of the fences 12 are arranged away from the support seat 13. The ends of the horizontal sections 121 of the fences 12 away from the vertical sections 122 are provided with protrusions 1211 that are upward and can pass through the through holes 131. When no material is placed on the support seat 13, the vertical sections 121 of the fences 12 are hinged to the horizontal sections 121 of the fences 12. The straight section 122 is away from the support seat 13 and drives the raised portion 1211 to pass through the through hole 131 and tilt upwards to the support seat 13. The fence 12 is away from the support seat 13 so that the distance between the two sets of opposite fences 12 is increased, which is convenient for material transportation and prevents the material from touching the fence 12 during transportation. When the material is placed on the support seat 13, the raised portion 1211 is pressed down under the action of the weight of the material, causing the vertical section 122 of the fence 12 to be set close to the support seat 13, automatically enclosing the material on the support seat 13 to prevent the material from tilting or spilling.

[0048] Furthermore, the vertical section 122 of the fence 12 includes a first vertical section 1221, a second vertical section 1222 and a transition section 1223. One end of the first vertical section 1221 is connected to the horizontal section 121 of the fence 12, and the other end is connected to the second vertical section 1222 through the transition section 1223. The transition section 1223 is arranged toward the support seat 13 away from one end of the first vertical section 1221. When there is no material pressing on the protrusion 1211, the moving distance of the end of the second vertical section 1222 in the direction away from the support seat 13 is reduced, thereby reducing the distance between the fence device and the cargo compartment wall, improving the loading capacity of the cargo compartment, and reducing space waste.

[0049] Furthermore, the width of each group of fences 12 is equal to the width of the material tray, ensuring that when a group of materials is stacked on the support seat 13, it only presses down the corresponding group of fences 12, without affecting the outward expansion of other fences 12, thereby facilitating the subsequent operation of materials.

[0050] The working principle of this embodiment is as follows: the material is stacked on the fork 7, the first linear sliding assembly 11 is driven, so that the base 1 moves linearly on the first linear sliding assembly 11 to the truck cargo box, and then the second telescopic electric cylinder 35 is driven to drive the fixed seat 4 on the X-shaped lifting frame 32 to descend, driving the feeding mechanism 5 to descend, and then by driving the first telescopic electric cylinder 22 to extend and retract, the first lifting mechanism 3 is driven to rotate on the base 1 under the action of the turntable 23, thereby driving the fork 7 toward the truck cargo box, and at the same time, the distance between the fork 7 and the cargo compartment door is detected by the two sets of first rangefinders 9. When the two sets of first rangefinders 9 detect that the distance is When the distances between the cargo compartment doors are equal, it means that the feeding end of the feeding mechanism 5 is parallel to the cargo compartment door, the operation of the rotating mechanism 2 is stopped, and then the transmission motor 54 is driven to drive the transmission belt on the conveyor belt assembly 53 to rotate, so that the second-layer sliding frame 51 moves on the fourth linear sliding assembly 52 on the bottom sliding frame 51. Since the bottom sliding frame 51 is connected to the second-layer sliding frame 51 through the second connecting block 57, the conveyor belt in the conveyor belt assembly 53 on the second-layer sliding frame 51 is driven, thereby making the third-layer sliding frame 51 on the fourth linear sliding assembly 52 on the second-layer sliding frame 51 move. The shovel fork 7 is moved on the moving assembly 52. The same principle is used to make the top sliding frame 51 move on the fourth linear sliding assembly 52 on the sliding frame 51 of the third layer, thereby driving the shovel fork 7 on the feeding frame 55 to move into the cargo compartment. At the same time, the two sets of second distance measuring instruments 10 detect the distance between the two sets of second distance measuring instruments 10 and the cargo compartment wall. When the two sets of second distance measuring instruments 10 detect that the distance between the two sets of second distance measuring instruments 10 and the cargo compartment wall is equal, the shovel fork 7 can be continued to be transported. If it is not equal, the first linear sliding assembly 11 is driven to drive the base 1 to move linearly until the two sets of second distance measuring instruments 10 detect that the distance between the two sets of second distance measuring instruments 10 and the cargo compartment wall is equal, and then the transport can be continued. The shovel fork 7 is delivered, and the first lifting mechanism 3 is driven downward. When the first pressure sensor 59 no longer receives pressure from the carriage 51, the roller 58 is placed in the fence device inside the cargo compartment. Simultaneously, the support block 41 no longer supports the carriage 51. The carriage 51 is supported at one end by the fixed seat 4 and at the other end by the roller 58. The conveyor motor 54 is then driven to move the four groups of carriages 51 into the cargo compartment. The gravity of the material is supported by the roller 58, significantly reducing the force on the hinge point between the bottom carriage 51 and the fixed seat 4. The gravity on the carriage 51 is also significantly reduced, providing a constant forward thrust. As the shovel fork 7 moves into the cargo compartment, the guide roller 143 abuts against the side of the fence device for guidance. The second pressure sensor receives pressure from the carriage 51. When it senses pressure, it indicates that the carriage 51 has deviated. The third telescopic cylinder 144 is then driven to extend and retract, driving the carriage 51 back until the second pressure sensor no longer receives pressure, stopping the extension and retraction of the third telescopic cylinder 144.

[0051] When the shovel fork 7 moves to the material stacking position, the second lifting mechanism 6 is driven to lower the shovel fork 7, and then the sliding frame 51 is recovered. At the same time, by driving the pushing electric cylinder 83, the pushing plate 82 is pushed away from the shovel fork 7, and the glass bricks on the shovel fork 7 are pushed onto the support seat 13. After the glass bricks are placed on the support seat 13, the weight of the glass bricks presses the raised portion 1211 downward, causing the vertical section 122 of the fence 12 to be set close to the support seat 13, automatically enclosing the glass bricks on the support seat 13 to prevent the glass bricks from tilting or spilling. When there are no glass bricks placed on the support seat 13, the vertical section 122 of the fence 12 is away from the support seat 13 and drives the raised portion 1211 to pass through the through hole 131 and tilt upwards to the support seat 13. The fence 12 is away from the support seat 13, which increases the distance between the two groups of opposite fences 12, facilitates the transportation of glass bricks, and ensures that the glass bricks will not touch the fence 12 during transportation.

[0052] It should be noted that the material loading device in this embodiment performs the material unloading operation in the same manner as described above.

[0053] To sum up, in the material loading device in this embodiment, the coordinated arrangement of the rotating mechanism 2, the first lifting mechanism 3, the fixed seat 4, the feeding mechanism 5, the second lifting mechanism 6, the shovel fork 7, the pushing mechanism 8, the first rangefinder 9 and the second rangefinder 10 realizes loading in a compact space, replaces manual loading of materials, and can load the same amount of materials as manual loading in a limited space, which not only reduces labor intensity but also improves loading efficiency; at the same time, through the arrangement of the fence device, it is possible to automatically enclose the materials on the support seat to prevent the materials from tilting or spilling.
